    摘要: The present invention relates to a manufacturing method for a phosphor suspension to be applied to an inner surface of a glass bulb of a fluorescent lamp, and a fluorescent lamp manufactured with use of the phosphor suspension.The method comprising the steps of kneading a mixture (38) of a small amount of solvent (32) including a thickening agent and a phosphor powder (30), and agitating the mixture after adding a solvent (40) including a thickening agent and a binding agent, and a metal compound as a coating agent (42) to the mixture.The fluorescent lamp pertaining to the present invention includes a phosphor layer formed by applying the phosphor suspension manufactured by the above-described method to the inner surface of the glass bulb, drying the suspension, and baking the suspension.Since the method pertaining to the present invention comprises the step of kneading, the phosphor particles included in the formed phosphor layer are densely arranged. As a result, the contact area between the phosphor particles and the inner surface of the glass bulb becomes large, and the phosphor layer hardly peels off. Also, since the phosphor particles are coated with the metal compound, the phosphor particles are prevented from reacting with Na included in the glass bulb and becoming degraded.
